GT4 Engine Removal, Engine Upgrade Options

Ok a few weeks ago started taking my engine apart, i did this as i have all the parts to recon the head on order and a day so to be delivered now so i decided to take the head off first even though usually you just drop the whole engine out the bottom. Also the car club on base has no bays available and they are changing locations in october. So i couldn't be ubikd waiting around and got right to it, i haven't spent too much time on it but all has gone quite well, I went home last week as my parents moved house so i thought i would visit. I de-coked the ports and got the head skimmed which revealed something interesting. As you will see on the pictures below you can see where my piston ring blew up on number 2 or 3 cant remember now. The head was off my old block which i unfortunately took out in a crash in 2007. This made my eyebrows as the guys who did most the work on reassembling the new engine never told me about this damage and leads me to believe whether they actually got the head skimmed at all when they did it:S. My own fault really as i was no where near as gen'd up on the car as i am now. Luckily the damage is all inside the gasket bracelet as shown on one of the pictures and i spoke to the engineering guys who skimmed they head and said it should be fine so i have been very lucky there. Another annoying thing i noticed is that 2 of the valve spring seats were missing, there is no damage just a bit more scratching on one of the valve recesses. If anyone has any of these spare please let me know.


















I have noticed 2 and 3 pistons and the ports on the head leading to them are much dirtier than the others, i am guessing cause this is a centre feed inlet manifold and not the designed side feed which i think you find on the st165.

you should do the 1ZZ-FE valve bucket conversion

Afraid i can't matey as the new titanium retainers can only go with new buckets and shims from supertech, either way the valve train is going to be lighter. Its not really a disadvantage, it would be if i had shim over bucket as there can fly out at high rpm.
